Investigators have no suspects, clues or motives in the slaying. Only a small window pane, which had been intact before the crime, had been removed from the window frame near the apartment's entrance, they said.

The apartment did not have electricity and Aguilar tended to keep her door open during the day, neighbors said. At night the apartment was lighted with candles and kerosene lamps, they said.

Lt. George Hagood, who is handling the case, said he plans to talk with Orange County investigators today to determine if there are connections between Aguilar's slaying and other recent murders and rapes in Orange County. Since Aguilar and her sister moved into the apartment at the end of June, people regularly have been seen visiting it, neighbors said.
